The embodiment of the invention provides equipment with an active noise reduction function. The equipment comprises a shell, a sound acquisition device, a controller and a loudspeaker. The shell is inan opening shape; the loudspeaker is arranged in the shell; the sound acquisition device is in communication connection with the controller; and the controller is in communication connection with theloudspeaker. The sound acquisition device is used for collecting environmental sound waves in the environment; and the controller is used for acquiring the environmental sound wave acquired by the sound acquisition device, determining a target sound wave according to the environmental sound wave and controlling the loudspeaker to produce sounds according to the target sound wave; and the target sound wave is a sound wave of which the intensity of the sound wave obtained by superposing the target sound wave with the environmental sound wave is less than a preset intensity. After the equipmentprovided by the embodiment of the invention is mounted on the seat, people can reduce the noises in the heard environment without wearing any earphone, earmuffs and other equipment, so that the damageto the hearing of people is reduced, and the comfort of people is improved.
Description
technical field [0001] The embodiment of the present invention relates to a device with an active noise reduction function. Background technique [0002] With the rapid development of my country's economy, people have higher and higher requirements for the comfort of the living environment. Among them, low-noise environment is one of them. People have low-noise requirements in offices, homes, and vehicles. [0003] In the related art, a noise-canceling earphone is a commonly used noise-canceling device, and people can reduce the noise they hear by wearing the noise-canceling earphone. [0004] However, wearing noise-cancelling earphones for a long time can cause great damage to hearing and also affect people's comfort. Contents of the invention [0005] The purpose of the embodiments of the present invention is to provide a device with an active noise reduction function, so as to reduce hearing damage and improve people's comfort. The specific technical scheme is as foll...
